Support for early data transmission through central unit/distributed unit function split

摘要

Methods, systems, and devices for wireless communications are described. The receiving device may receive the information at a central unit of the receiving device, and the central unit may identify from the information a hash calculated based at least in part on the data portion of the message received by the distributed unit of the receiving device. . The receiving device may verify the integrity of the data portion of the message based at least in part on the hash at the central unit. Additionally or alternatively, the distribution unit of the receiving device may verify the integrity of the data portion of the message. The receiving device may authorize one or more user plane tunnels with the distribution unit to forward the data portion of the message from the distribution unit to the central unit after processing at the distribution unit based at least in part on the integrity check.
